# Industrial Specification: Fastener System

## 1. Technical Definition
A mechanical assembly designed to securely join and fasten panels together within a larger panel joint system.

## 2. Engineering Reasoning & Causal Matrix
> **Operational Intelligence**: Designed for **0.5-25 kN clamping force, 0.1-2.0 mm joint gap tolerance, -40°C to 150°C temperature range**. Failure boundary: **Shear stress exceeding 400 MPa for steel fasteners (yield strength), clamping force dropping below 0.3 kN, joint gap exceeding 2.5 mm**, Mechanism: **Stress concentration at fastener holes exceeding material yield strength (Hooke's Law: σ = F/A), thermal expansion mismatch (ΔL = αLΔT) causing joint loosening, fretting corrosion at contact interfaces**.

### 2.2 FMEA (Failure Mode & Effects Analysis)
| Event Trigger | Severity | Failure Mode | Mitigation Strategy |
| :--- | :--- | :--- | :--- |
| Vibration-induced loosening at frequencies above 200 Hz (resonance) | 8 | Fastener preload loss exceeding 30%, joint separation, panel misalignment | Torque-to-yield fasteners with 0.2% proof stress control, thread-locking compounds (e.g., anaerobic adhesives), anti-vibration washers with 15 N·m minimum locking torque |
| Galvanic corrosion between dissimilar metals (ΔE &gt; 0.25 V electrochemical potential) | 8 | Fastener cross-sectional area reduction exceeding 20%, tensile strength degradation, catastrophic shear failure | Material pairing with &lt;0.15 V potential difference (e.g., stainless steel-aluminum with insulating sleeves), zinc-rich epoxy coatings (85% Zn by weight), cathodic protection with 1.1 V sacrificial anodes |
